Application of CBR in VR-based test and simulation system

This paper first introduces the concept of VR-based test and simulation. In a VR-based test and simulation system (VTSS), the test processes are interactively planned, optimized and simulated in a virtual test environment generated by computer, aiming at eventually performing tests completely in virtual test environments. To make VTSS intelligent and practical, the technique of case-based reasoning (CBR) is introduced into the system. With ultrasonic non-destructive testing (NDT) as the technical background, a prototype of the system is detailed in the paper. The conclusion is that CBR can play a very important role in VTSS.
